- James Mishler once played an rpg with Gary Gygax. That's gives James a Gygax Number of 1.
- I once played OD&D with James, but never played with Gary. That makes my Gygax Number 2.
- If you have played an RPG with me, the biggest Gygax Number you can have is 3. For example, chgowiz and I played Labyrinth Lord together at my local con. Assuming he never played with Gygax or James, he would have a Gygax Number of 3 and the biggest Gygax Number his gaming buddies could have would be 4.
With the linking criteria set as "played an rpg together" there will be people in the hobby to whom no Gygax Number can be assigned. Until I went to my first convention I couldn't possibly have a Gygax Number, as I started out as an isolated kid with a Basic set and my original play group all learned the game from me.
